 【标题】Analysis on voltage oscillation of a mid-frequency series resonant inverter for DRMP coils on J-TEXT

 【作者】Long-jian Liua, Ke-xun Yua, Ming Zhanga, Jie-yin Nana, Guo-zhong Jianga, Bo Raoa,, Xuan Lia,

 【摘要】This paper deals with the voltage oscillation of an AC power supply for generating dynamic magnetic perturbation (DRMP) on J-TEXT. The power supply is a series resonant inverter with a matching transformer. It was noted that the high-voltage oscillation at transformer primary side is caused by an interaction between the line inductance and the stray capacitance of the matching transformer at switching transitions. In order to reduce the high-voltage oscillation and consider the requirement for soft-switching technique simultaneously, the switching frequency should be chosen properly by fine-tuning. The dead time should be chosen according to the relative size of minimum required dead time for protection and the optimal dead time.Keywords

 【篇名】宽电压输入多路输出逆变控制开关电源设计

 【摘要】 程控电源是一种智能化电源,它能根据不同环境的需要为其他设备提供合乎规格的能源,不仅广泛应用于自动测试系统中,而且可以作为一种通用的动力源,在工业生产和实验研究等领域中起着重要的作用。尽管目前市场上的程控电源种类不少,且其调节范围、控制精度等性能指标亦有多种选择,但由于其与上位机接口多为GPIB或RS-232接口,交流输入电压范围固定,并且体积很大,价格昂贵,因此很难为实际用户组建小型自动测试系统所接受。针对这些问题,本文研制了一种基于USB接口控制的宽范围输入电压的程控开关电源。本文首先提出了程控电源的总体设计方案,接着使用单片开关电源芯片TOPSwitch设计出了宽范围电压输入的小功率反激式开关电源,对开关电源中的核心功率转换部件——高频变压器进行了详细分析设计;其次,使用状态空间平均法推导了反激式开关电源功率级主电路的低频小信号模型,并分析了开关电源反馈环路的传递函数,进而对整个开关电源系统进行了系统建模并对其稳定性进行了分析;再次,以设计出的开关电源作为初级电源,使用改变反馈环路反馈量大小的控制策略,在理论上实现了电源输出电压幅值的线性调节;最后,以集成了USB功能控制器的Soc片上系统C8051F320作为控制电路的核心控制器,设计了程控电源的硬件控制电路,并使用C51语言编写了单片机的固件程序以及使用Visual Basic语言开发了程控电源上位机应用软件程序。通过对研制的小功率程控电源进行实验及测试,结果表明,其主要性能指标,如电压调整范围、电压调整精度、负载调整率、输出电压纹波等均达到了设计要求。本文研制的基于USB接口的程控电源已应用于实际项目中,实践表明,与常见的GPIB及RS-232接口的程控电源相比,其易用性和易操作性大大加强。

 Hard-switching and soft-switching two-switch flyback PWM DC-DC converters and winding loss due to harmonics in high-frequency transformers .

 【摘 要】The flyback pulse-width modulated PWM) DC-DC power converter is a very important circuit in switching mode power supply SMPS) converters for low power applications. The main drawback of the conventional single-switch flyback converter is the high turn-off voltage stress suffered by the switch. The high voltage transients are caused by the resonant behavior of the transformer leakage inductance and the transistor output capacitance, resulting in ringing superimposed on the steady-state switch voltage level. This requires a transistor with higher voltage rating. However, a transistor with higher voltage rating has higher on-resistance causing higher conduction loss. The high voltage ringing also increases the switching loss. In addition, the switch voltage stress is not easily predictable because it is difficult to determine the magnitude of ringing during the design stage. The two-switch flyback DC-DC converter is an extended version of the single-switch flyback converter. The circuit arrangement with an addition of a power transistor and two clamping diodes to the conventional single-switch flyback converter leads to the two-switch flyback PWM DC-DC converter, which effectively reduces the switch overvoltage and eliminates the uncertainty of its value. The clamping diodes in the two-switch flyback converter clamps the voltage across each switch to the DC input voltage and also provide a path to return most of the energy stored in the transformer leakage inductance to the DC input source. In the first part of this research, detailed steady-state analyses of the two-switch flyback PWM DC-DC converter for continuous conduction mode CCM) and discontinuous conduction mode DCM) are performed. The transistor output capacitance and the transformer leakage inductance are included in the analyses. Design equations for both CCM and DCM operation modes are derived. Furthermore, by incorporating an active clamp circuit into the hard-switching two-switch flyback converter, a new soft-switching two-switch flyback converter, namely, zero-current transition ZCT) two-switch flyback is proposed. The principle of circuit operation, steady-state analysis, equivalent circuits, converter steady-state waveforms, and design procedure of the proposed ZCT two-switch flyback converter is presented. The key features of the proposed soft-switching converter are 1) the voltage stresses of the main switches are reduced to DC input voltage VI , and 2) all the semiconductor devices are turned off under zero-current ZC) switching condition. Clamping of the switch overvoltages and reduction in switching loss are achieved in the proposed ZCT two-switch flyback converter. Saber Sketch simulation and experimental results of the hard-switching and the proposed ZCT soft-switching two-switch flyback converters are presented to validate the theoretical analyses. High frequency HF) transformers used in PWM converters, such as flyback transformers conduct periodic nonsinusoidal currents, which give rise to additional winding losses due to harmonics. In the second part of this research, a theory is developed to find the harmonic winding loss in an HF transformer conducting periodic nonsinusoidal current. Dowells equation is used to determine the winding resistances due to eddy currents as a function of frequency. Both skin and proximity effects are taken into account. Fourier series of the primary and secondary current waveforms in a two-winding flyback transformer and the primary and secondary winding resistances are used to determine the primary and secondary winding power losses at various harmonics for both CCM and DCM cases, respectively. The harmonic winding loss factors FRph and FRsh are introduced. The theory is illustrated by the case study of flyback converter for both CCM and DCM operations.
